目的 对 30例散发性肾母细胞瘤WT1基因缺失进行检测 ,并分析其与组织类型的关系。方法 采用Southern印迹分子杂交技术。结果 2例WT1基因内缺失为间质优势型肾母细胞瘤。结论 肾母细胞瘤的病因学十分复杂 ,WT1基因缺失可能与间质优势型肾母细胞瘤的发生有关。
Objective To detect the deletion of WT1 gene in 30 cases of sporadic nephroblastoma and analyze its relationship with the type of tissue. Methods Southern blotting molecular hybridization was used. Results Two cases of WT1 gene deletion was interstitial nephroblastoma. Conclusion The etiology of nephroblastoma is very complicated. The loss of WT1 gene may be related to the occurrence of interstitial nephroblastoma.
